  • Patent number: 8760001
    Abstract: A supply circuit is provided for the electrical supply of a vehicle. Here, a battery for generating a battery supply voltage and a step-up converter for generating an intermediate voltage from the battery supply voltage are provided. A temporary store is supplied from the intermediate voltage and serves for storing electrical energy. A step-down converter for generating a first consumer voltage for supplying a first consumer from the intermediate voltage and a second step-down converter for generating a second consumer voltage for supplying a second consumer from the intermediate voltage are provided. A control circuit serves to control the step-up converter, the first step-down converter and the second step-down converter.
